在我看来，这是你最快的方法;

在visual studio代码上打开集成终端(查看>集成终端) 输入“node filename.js” 按回车键

注意:节点设置需要。(如果你有自制程序，只需在终端上输入“brew install node”)

注2:如果你还没有自制和节点，强烈推荐。

祝你有愉快的一天。

对于windows:只需将.js文件的文件关联更改为node.exe

1) Take VSCode
2) Right click on the file in left pane
3) Click "Reveal in explorer" from context menu
4) Right click on the file -> Select "Open with" -> Select "Choose another program"
5) Check box "Always use this app to open .js file"
6) Click "More apps" -> "Look for another app in PC"
7) Navigate to node.js installation directory.(Default C:\Program Files\nodejs\node.exe"
8) Click "Open" and you can just see cmd flashing
9) Restart vscode and open the file -> Terminal Menu -> "Run active file".

这很简单，当你在VS Code中创建一个新文件并运行它时，如果你还没有配置文件，它会为你创建一个，你唯一需要设置的是“program”值，并将其设置为你的主JS文件的路径，如下所示:

{
    "version": "0.1.0",
    // List of configurations. Add new configurations or edit existing ones.  
    // ONLY "node" and "mono" are supported, change "type" to switch.
    // ABSOLUTE paths are required for no folder workspaces.
    "configurations": [
        {
            // Name of configuration; appears in the launch configuration drop down menu.
            "name": "Launch",
            // Type of configuration. Possible values: "node", "mono".
            "type": "node",
            // ABSOLUTE path to the program.
            "program": "C:\\test.js", //HERE YOU PLACE THE MAIN JS FILE
            // Automatically stop program after launch.
            "stopOnEntry": false,
            // Command line arguments passed to the program.
            "args": [],
            // ABSOLUTE path to the working directory of the program being debugged. Default is the directory of the program.
            "cwd": "",
            // ABSOLUTE path to the runtime executable to be used. Default is the runtime executable on the PATH.
            "runtimeExecutable": null,
            // Optional arguments passed to the runtime executable.
            "runtimeArgs": [],
            // Environment variables passed to the program.
            "env": { },
            // Use JavaScript source maps (if they exist).
            "sourceMaps": false,
            // If JavaScript source maps are enabled, the generated code is expected in this directory.
            "outDir": null
        }, 
        {
            "name": "Attach",
            "type": "node",
            // TCP/IP address. Default is "localhost".
            "address": "localhost",
            // Port to attach to.
            "port": 5858,
            "sourceMaps": false
        }
    ]
}

在Visual Studio Code中运行javascript有很多方法。

如果您使用Node，那么我建议使用VSC中的标准调试器。

我通常创建一个虚拟文件，比如test.js，在那里我做外部测试。

在存放代码的文件夹中，创建名为“”的文件夹。然后创建一个名为launch。json的文件

在此文件中粘贴以下内容并保存。现在您有两个选项来测试您的代码。

当你选择“Nodemon Test File”时，你需要把你的代码放在Test .js中进行测试。

要安装nodemon以及更多关于如何在VSC中调试nodemon的信息，我建议阅读这篇文章，它更详细地解释了发布的第二部分。json文件和如何调试在ExpressJS。

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Nodemon Test File",
            "runtimeExecutable": "nodemon",
            "program": "${workspaceFolder}/test.js",
            "restart": true,
            "console": "integratedTerminal",
            "internalConsoleOptions": "neverOpen"
        },
        {
            "type": "node",
            "request": "attach",
            "name": "Node: Nodemon",
            "processId": "${command:PickProcess}",
            "restart": true,
            "protocol": "inspector",
        },
    ]
}

集成终端的快捷方式是ctrl + '，然后键入node <filename>。

或者，您可以创建一个任务。这是唯一的代码在我的tasks.json:

{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "0.1.0",
"command": "node",
"isShellCommand": true,
"args": ["${file}"],
"showOutput": "always"
}

从这里创建一个捷径。这是我的keybindings.json:

// Place your key bindings in this file to overwrite the defaults
[
{   "key": "cmd+r",
"command": "workbench.action.tasks.runTask"
},
{   "key": "cmd+e",
"command": "workbench.action.output.toggleOutput"
}
]

这将在命令面板中打开“运行”，但你仍然需要用鼠标键入或选择你想要运行的任务，在这种情况下是节点。第二个快捷键切换输出面板，它已经有一个快捷键，但这些键彼此相邻，更容易使用。

用npm安装nodemon Init nodemon: npm Init 打开的包。Json，并将其更改为: ｛ “名称”:“JavaScript”, “版本”:“1.0.0”, “描述”:“”, “主要”:“{文件名}. js”, "脚本":{ "test": "echo \"错误:没有测试指定的\" && exit 1"， "start": "nodemon {filename}.js" }， “关键词”:[], “作者”:“”, “许可证”:“ISC” ｝ 在终端上写这个命令:npm start
